of which are formed-two ribs 14 14 consti- I tuting' a cam path said cylinder 10 with its ribs 14 constituting a cam-ring or'cylinder..-

The shaft carry ing one gear 123 and feed-wheel 124 can be made to approach orrecede from its complemental gear-wheel 123 and feed-wheel 124 on the opposite side of the throat of the cylinder 5 in order to accommodate the feed-wheels 124 to the size of the goods being made on the machine. This adjustment of the feedwheels is effected by a screw-shaft 126 indicated in Fig. 3. 127 (see Fig. 3) represents a bracket secured to the rear face of the ring 2 and supporting a hub 128 in" which is arranged a short shaft 129. Upon the rear end of this shaft are mounted two pulleys 130 131. A belt 132 connects thepulley 131 with the pulley 15. By this means rotation is imparted to the shaft 129. 133 represents a belt connecting the pulley'13O with a pulley 134 on the end of the shaft 122. The movement imparted to the shaft 122 is communicated to gears 123 and by them to the complemental feed-wheels 124 124. The feed mechanism above described takes its motion from the main driving pulley.

The warp mechanism of the machine is carried by the cylinder 3 and ring 2-. In the form of the machine here shown eight warp units are illustrated, but as "many may be employed as desired. These warp units are identical with one another and a description of onewill suflice for all.

70 re resents a rack arranged in suitable ways 0 a bracket 7O carried by the rear side of the rin 2. The rear end of this rack carries a roller 71 arranged between the ribs 14 of the cylinder 10, whereby a recipro eating or in-and-out motion is given to the rack 70, such reciprocation being in direct ratio to the rotation of the gear 8.

72 (Figs; 1, 3 and 15) represents a bracket carried by the front side of the ring 2. This bracket is formed with ahead 73 which is arranged'with a short shaft or pintle 74. On the rear end of this pintle is secured a gear 75 whose teeth are cut to mesh with I those of the rack 70 (Fig. 15). Upon the jfrontend of this pintle is secured the gear or pinion 76.

77 represents a plate carried on the front To the lower end of the shaft of each end efthebracket 72 and formed on its front side with-two parallel grooves 78 78 in each of which is arranged a rack 79 with their teeth facing each other upon the opposite sides of and in mesh with the teeth of the pinion 76 (Fig.. 16).

7 7" represents a plate secured to the top of the plate 77 by means of bolts 77* to maintain the racks 79 in their grooves. The arrangement is such that the reciprocation of the rack 7 0 due' to the action of the cam on the cam-cylinder 10 gives a reciprocating ion 76, thereby giving a simultaneous reei 'rocating motion in opposite directions to t e two .racks 79. The upper endof each rack .79 is bent as at 80 and in the free end of said arm is arranged a bolt 80*. The latter is formed with a head 80". A nut 80 upon the opposite end of said bolt serves to inch the end of the arm 80 between the ead and the nut and, thus maintain the head 8'0 rigidly. in position; The head 80 is formed withja perforated ear 80 ear pivotally securedto the car 80 by means of a bolt 141. To the ear 140 is secured the rear member 142 of a warp-spool. The hub 143 of this spool is extended and has its free end screw threaded at 144 to receive a thumb-nut 145.

146 represents the outer member of the spool adapted to be arranged upon the screw-threaded extension 144, the spool beingheld in position on the hub 143 by means of nut 145. To the periphery of the member 146 is 'securedan. eye or guide 147 through of the warpjin the spool. A warp passes ways hereinafter described to the front end woven in with the weft.

The parts are so timed that the racks 79 reciprocate just inadvance of the nose of the shuttle hereinafter described, thereby raising one warp 81 and lowering the other, forming the shed between the war s 81 through which the shuttle with its we t passes. This operation is repeated at each warp unit. In the form of the machine here shown, there being two shuttles, it will be understood that each is operated recisely as one shuttle, thus making the machine practically double, the timing of the warp units being controlled by the cam path 14 in the cylinder 10, this cam path in this form of machine being double, that is to say 369 of this cam path are divided intotwo units of 180, each of said units being identical.

The ring 20 near its periphery and inside the flange 20 'is; formed with four bearings '21 arranged at an angle of 90 to each'other, although the num'-' ber and arrangement may be varied ifdesired.

this arrangement the pinions 30 are all given the same eripheral speed and together with run.

A bracket 28 is secured to eachrack 26 midway between the ends of the spider 2'2. the top of bracket 28 is secured an ear sub stantially-like the ear (Fig; 24). I The car 80? has pivoted; to it an ear 140 that supports a spool of weft 29. The Warp spools and the shuttle-spools as .well as their manner of;

mounting are the same-so that the illustration of Fig. 24 of the warp spools willsuflice, the purpose of the adjustment being to enable thespool t6 be tilted for applying coilpsor the like of warp or weft material. weft 29 passes from the shuttle-spool through a shed so that the forward end of eachshut- "the case may be, may be varied.

of movement with relation to the center-of up is required.

Inasmuch as the pinions 33 are ar-'- ranged 90 apart it follows that one of these pinions will always be in engagement with guide eye 1 17 and the ring 300. Each of the racks'26 carries a s iderm the eye fl l47fthen through tensionpins 35. and through the eye 35 tothe' throat. of the m achine'. I

In a machine for forming tubes, a cylinder or throat, a series of warp guiding members arranged about said throat, means connected to each member for reciprocating it to form a shed, arranged to maintain a substan tially constant distance between said member and said throat, a shuttle device ar.

ranged to travel in the shed so formed, and means for operating said shuttle device.

2. In a machine for formin tubes, a cylinder or throat, a weft shutt e arranged to travel about said throat, a series of warpformed with a thread-e e or warp-guide, an

3. In a machine for forming tubes, a horizontal cylinder or throat, a warp ring arranged about said cylinder, a series of pairs of warp s ools, a series of airs of members supporte by said ring, an each connected to one of said spools, a cam-ring supported by said cylinder, and connections between said cam-ring and said members.
